The problem is that this indicates very strongly that you do not 
understand the _mathematical_ definition of a surface.  A surface does 
not necessarily (nor does it uniquely in any case) have an embedding.  
That is, mathematically speaking, for generalized surfaces, there is 
no "through" to cut through to get your "correct" diameter of a 
"planar circle."  The concept is quite simply misguided.
